We report results from our recent study on charm and anticharm quark pair production in the next-to-leading order in QCD from the quark-gluon formed in heavy ion collisions at the Large Hadron Collider (LHC) and its dependence on the number of charm quark pairs produced from initial hard scattering, the charm quark mass, and the temperature and formation time of the quark-gluon plasma.
